Propellor too big?

[SeaMasterZ@aol.com]

up for grabs is an 11 x 14 (or so the guy thinks) prop for a '60 40 horse Johnny/Rude - <br /><br />and of course I have two questions<br /><br />1 - isnt a 9.75 x 11 what is usually put on the smaller outboards, making this prop a bit too big<br /><br />2 - since it is going on an aluminum boat with another motor, shouldnt it be a little big anyway to keep it from over revving? (will be on the fiberglass for a while, but only til the end of the season)<br /><br />thanks <br /><br />(note I kept it short and to the point!)

Ray,<br />My 1960 40 hp had a 10 1/2 X 12 on it. And my 1958 35 Hp came with a 10 X 11 on it.

Ray - Others might be able to give you some advice but I suspect that you might get better results if you gave a tiny hint on the boat you are putting it on.

Re: Propellor too big?

so little is right, if im not mistaken the lenght of the boat and the hp of the motor can give you a starting point for a prop. example is my evinrude 50 now has a 17p 14ft bowrider but if you were to put that motor on a 17ft boat you would need around a 13p maybe a 15p. but your main objective is to reach 5200-5500rpm wot.

mea culpea ... ive talked about that danged 18 Starcraft runabout so many times, I figgered yall were tired of hearing about it, and I really am not sure how to answer ... the boat is light, even with its new floor in and a hunk of carpet, its not going to be much heavier, but being a big guy with buddies, (boat loading will usually run nearly 1000 pounds in crew and gear not counting the Go Go Gear, gas and engines and a few batteries) I dont know if that counts as lightwieght<br /><br />if anyone has a decent prop to fit a 66 Johnson 40, let me know, especially within a hundred miles of philly, Im a parts buyin junkie, lol<br /><br />

Might be a little on the large side but you could always get a bigger johnson to hang it off Keep laughing Ray
